The New Astronomical Frontier of Interstellar Objects

open access: yesAstrobiology, 2021
The upcoming commencement of the Vera C. Rubin Observatory's Legacy Survey of Space of Time (LSST) will greatly enhance the discovery rate of interstellar objects (ISOs).

Capture of interstellar objects II: by the Solar system [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
Capture of interstellar objects (ISOs) into the Solar system is dominated by ISOs with asymptotic incoming speeds v∞ < 4 km s−1. The capture rate is proportional to the ISO phase-space density in the Solar vicinity and does not vary along the Sun’s ...

The Distribution of Earth-impacting Interstellar Objects

open access: yesThe Astrophysical Journal
In this paper we calculate the expected orbital elements, radiants, and velocities of Earth-impacting interstellar objects. We generate a synthetic population of ∼10 ^10 interstellar objects with M-star kinematics in order to obtain ∼10 ^4 Earth ...

Interstellar Objects Follow the Collapse of Molecular Clouds [PDF]

open access: yesThe Astrophysical Journal, 2021
Interstellar objects (ISOs), the parent population of 1i/'Oumuamua and 2i/Borisov, are abundant in the interstellar medium of the Milky Way. This means that the interstellar medium, including molecular-cloud regions, has three components: gas, dust, and ...

Close Encounters of the Interstellar Kind: Examining the Capture of Interstellar Objects in Near Earth Orbit

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
Recent observations and detections of interstellar objects (ISOs) passing through the solar system have sparked a wave of interest into these objects. Although rare, these ISOs can be captured into bound orbits around the Sun.

X-Rays Trace the Volatile Content of Interstellar Objects

open access: yesThe Astrophysical Journal, 2023
The nondetection of a coma surrounding 1I/‘Oumuamua, the first discovered interstellar object (ISO), has prompted a variety of hypotheses to explain its nongravitational acceleration.

ATLAS Photometry of Interstellar Object 3I/ATLAS

open access: yesThe Astrophysical Journal Letters
We present calibrated Asteroid Terrestrial-impact Last Alert System (ATLAS) photometry of the interstellar comet 3I/ATLAS (C/2025 N1) from March 28 through 2025 August 29, obtained with the five-site, robotic ATLAS network in the c (420–650 nm), o (560 ...

Interstellar objects and exocomets

open access: yes
In this chapter we review our knowledge of our galaxy's cometary population outside our Oort Cloud - exocomets and Interstellar Objects (ISOs). We start with a brief overview of planetary system formation, viewed as a general process around stars.

Capture of interstellar objects I: the capture cross-section [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
We study the capture of interstellar objects (ISOs) by a planet-star binary with mass ratio q ≪ 1, semi-major axis ap, orbital speed vc, and eccentricity ep.

Interstellar Objects in the Solar System

open access: yes
1I/`Oumuamua and 2I/Borisov are the first macroscopic interstellar objects to be detected in the solar system. Their discovery has triggered a tsunami of scientific interest regarding the physical properties, dynamics and origin of the so-called ...
